Abstract (en)
Disclosed are a nickel hydroxide powder and a method for producing the same. The nickel hydroxide powder comprises a particle in the form of sphere, an average particle diameter of 0.1 µm or more and 30 µm or less, and the amount of the particles having a diameter of 0.7 times or more and 1.3 times or less the average particle diameter of 80% by weight or more based on the total amount of particles. The method for producing a nickel hydroxide powder comprises the steps of (1) to (4):(1) injecting a solution containing a nickel salt through a pore into a liquid mutually insoluble with the solution to obtain an emulsion including solution as a dispersed phase and the liquid as a continuous phase;(2) gelating the emulsion;(3) separating the dispersed phase from the obtained gel to obtain a cake; and (4) drying the cake.
